TRENTON — If it were up to New Jersey voters, the 2016 presidential race would be a battle between Hillary Rodham Clinton and Gov. Chris Christie, according to a poll released by Kean University today.

Meanwhile, the survey shows voters continue to struggle with a key question in this year's election season: Who is Barbara Buono?

According to the poll, 67 percent of Democratic voters said they would support Clinton — the former First Lady, U.S. Senator from New York and Secretary of State — for president. Vice President Joe Biden finished a distant second, with 13 percent. New York Gov. Andrew Cuomo drew 8 percent.

"There's a sense that the 2016 Democratic presidential nomination is Hillary Clinton's for the asking," Terry Golway, director of the Kean University Center for History, Politics, and Policy, said in a statement. "This poll of New Jersey Democrats certainly confirms that thinking."

As for Republican voters, 41 percent said they'd support Christie for president. U.S. Sen. Marco Rubio of Florida was second with 18 percent.

The poll also shows that Christie's approval rating at home continues to soar: 71 percent of the poll's 1,000 respondents said they either strongly approved or somewhat approved of his performance. Sixty-one percent of Democrats approve of the job he's done, as well as 66 percent of African-Americans, 61 percent of those who consider themselves liberals, and 72 percent of moderates.

Buono, a state senator from Middlesex County, didn't fare as well: 64 percent of voters said they were either not very familiar or not at all familiar with her. Only 4 percent said they were unfamiliar with Christie.
